DRAFT-TRUCK FOR AGRICULTLIRAL IMPLEMENTS.

Patented Oct, 16, 1906.

' Application filed July 14,1906. Serial No. 326.270.

To ti/Z whom it may concern:

Be it known that I, HARRY V. SMITH, acitizen of the United States, residim'g; at Sugar Grove, in the county of Kane and new and useful Improvements in Draft-Trucks for Agricultural Implements, ofwhich the following -is a specification. v

This invention is a draft attachment for agricultural adapted for disk harrows, but it will be apparent that the attachment is not limited to such use, but may be applied tovarious other forms of harrows .or to other agricultural implements of a similar kind.

The invention constitutes an improvement in the usual tongue connections to a harrow, and has for its object to relievethe horses of the weight side strain or side draft incident to of the implement.

he invention comprises a truck whichcarries the front part of the harrow and provided with a swivel g connection "adjustable in various ways, as will be-more fully hereinafter described. I

In the accompanying drawings, Figure 1 is a side elevation of a disk harrow provided with the invention. Fig. 2 is a partial plan view, the upper parts of the implement being the use removed to show the truck'more clearly.

Fig. 3 is a detail in perspective showing the connection between the truck and the implement. l

Referring specifically to the drawings, indicates disks of the usual type mounted on shafts 11, carried in hanger-frames 12. The front beam 13 supports the seat, and a whiffletree or draft-evener is attached thereto by the usual strap and bolt. This beam isfastened at its rear end upon a cross-beam 14,- preferably a hollow metallic shape, connected at the ends by draft or supporting bars 14- to the disk-shafts 11, which have the ordinary means for allowing the swing of the gangs to vary line of draft. This variation or adjustment is effected by a lever 13*, fulcrumed on the beam 13 and connected atits lower end by bars 13 to the axles 11,

The supporting-truch-for the front part of l the harrow comprises a tongue 19 and an arched axle 20, provided at the ends with implements, andparticularly and between of the implement and also of ariy wheels and connected to the tongue by brace-bars '21. The axle-bar 20 may be formed of flat metal, but at the middle it has a round part 20, which extends through a loop 20 on the tongue. I

A swiveling and supportingconnection between the truck and the hStIIOW-fI'QL provided by means of a s uaredbolt 17, having a round head 1 7 whic fits in a socket 18 on top of'the} tongue 19,. Said bolt is carried by a bracket consisting of two plates 16*, bolted, respectively, .to the top and bottom of the front end of the beani 13. The bolt extends through square holes in these plates the plates is provided with a collar 16, which may be set on the bolt by a setscrew 16 y raising or lowering the collar the relative angle of the parts and the height of the whiflietree 15 arevaried or adjusted. 1

It will .be seen that the weight of the implement is supported at the front upon the truck described and the team carries no weight except that of the tongue 19 of the t uck. The ball-and-socket joint provides a the angle of the disks to the u .lower en fitting in said 'swivelin connection which allows a certain amount of side swing without throwing the tongue or the strain thereof upon the draftanimals- The bolt 17 allows the line of draft, and consequently the depth of cut, to be varied. The location of the whifiletree 15 on the beam 13 affords a comparatively close and direct hitch to the harrow, which is nection between the truck and the implement..-

claim- A-draft attachment for implements, comprising a wheeled truck having a socket-on top, a s

at the front of the implement having bracket provided with a square hole through which the bolt extends, and an adjustable oollaron the bolt under the bracket;
